Properly Upgrading an Existing CCTV Surveillance System

Starting from the ground up usually isn’t the best approach when upgrading security systems. If all a surveillance system needs is an update or a quick fix to a persisting issue, it may be better to simply replace parts. While it can be both challenging and expensive, it’s best to take into account your own situation. Rebuilding from scratch is often more hard on yourself and your hard-earned finances, so it’s best to see what your options are before acting on a plan.

Today’s surveillance networks utilize Digital Video Recorders (DVR) instead of older VCRs. Think of the DVR as the brain of a network, converting a camera’s analog feed to a digital feed on screen. Start with a DVR unit that records sufficient amounts of data, while also having an acceptable framerate and resolution. It is also important to make room for necessary expansion when finding a suitable device for your surveillance system.


It is unnecessary to completely replace old equipment in the process of building a new system. In fact, it is often more expensive and time-consuming. If old analog cameras still work fine there is no need to remove them completely, as long as they share compatibility with the new recording device. Hybrid video recorders permit existing cameras to remain in place, and still adequately record their feeds while allowing installation of newer cameras. Placing focus on expanding an existing network before removing it altogether saves a lot of money in the process.


Another complication when putting together a surveillance system is camera placement. It necessary to know where and how a camera can be used effectively. For example, a large area that has one camera in a corner will work best if it can pan, tilt and zoom. Since upgrading existing cameras will involve downtime, it is best to use that time to tackle system-wide performance issues. While upgrading, it is important to address persistent performance issues such as grainy feed, poor camera angles and faulty wiring. Knowing the difference between what works and what is broken also cuts down on costs.


In short, allowing support for current tech along with future expansions creates multiple options for the entire system. A hybrid video recorder allows support for old network cameras and installation of at least a couple new cameras. Starting from scratch will be entirely unnecessary as long as everything is in place and functions correctly.
